چکیده

Abstract A study of nonlinear waves in liquid-gas mixtures with the consideration internal effects is an important problem both fundamental and applied fluid mechanics. Investigation gas-liquid allowance for task These problems often arise industrial processes such as oil gas production, hydrocarbons pipeline transportation, gas-saturated fluids flow pipelines, etc. In this work, we investigate effect electric field on wave propagation a bubbly liquid. Numerical simulations have been conducted to described by Burgers-Korteweg-de Vries equation. The numerical showed that electrokinetic significantly affect process. amplitude gradually decreases when size bubble decreasing electrical potential increases. good agreement obtained results our previous predictions found.

Effective equations for wave propagation in bubbly liquids

We derive a system of effective equations for wave propagation in a bubbly liquid. Starting from a microscopic description, we obtain the effective equations by using Foldy's approximation in a nonlinear setting. We discuss in detail the range of validity of the effective equations as well as some of their properties.

Effect of direct bubble-bubble interactions on linear-wave propagation in bubbly liquids.

We study the influence of bubble-bubble interactions on the propagation of linear acoustic waves in bubbly liquids. Using the full model proposed by Fuster and Colonius [J. Fluid Mech. 688, 253 (2011)], numerical simulations reveal that direct bubble-bubble interactions have an appreciable effect for frequencies above the natural resonance frequency of the average size bubble. Based on the new ...

Shock Propagation in Polydisperse Bubbly Liquids

We investigate the shock dynamics of liquid flows containing small gas bubbles, based on a continuum bubbly flow model. Particular attention is devoted to the effects on shock dynamics of distributed bubble sizes and gas-phase nonlinearity. Ensemble-averaged conservation laws for polydisperse bubbly flows, together with a Rayleigh–Plesset-type model for single bubble dynamics, form the starting...

A Vlasov equation for pressure wave propagation in bubbly fluids

The derivation of effective equations for pressure wave propagation in a bubbly fluid at very low void fractions is examined. A Vlasov-type equation is derived for the probability distribution of the bubbles in phase space instead of computing effective equations in terms of averaged quantities. This provides a more general description of the bubble mixture and contains previously derived effec...
